Abstract
A hard coating containing at least one layer including chromium, aluminum, tantalum and nitrogen as main components and a chemical composition (AlaCrbTac)N in which the following conditions are satisfied: a=x, (1−c), b=(1−x)·(1−c), 0.60≦x≦0.70, and 0.01≦c≦0.5. The layer has an X-ray diffraction peak intensity ratio of I200/(I200+I111)≧0.25. The application also relates to a reactive arc ion plating PVD process for making the hard coating.
